Double-layer 100% cotton muslin swaddling blanket. The fabric’s light, open weave allows a baby’s body temperature to regulate itself naturally, helping to reduce the risk of overheating. The double layer of muslin ensures baby stays comfortably warm on cold nights and brisk walks through the park. The more you wash aden + anais wraps, the softer they get. aden + anais wraps are extra large, measuring 47” x 47”, so that new and seasoned mums alike can swaddle babies of all sizes with ease. Traditionally used for swaddling, our wraps can also be used as burp cloths, nursing and stroller covers, portable crib sheets, stroller and car seat liners, tummy time blankets, change table covers and more.
